I'm trying to write a code where I can give two different properties in the graph given the value of psi.
For example, I have a function where I specify psi_value:
I would like for it to do something like this:
for psi_value= .05 or .15 or .25 or .35;
for psi_value_j=.1 or 2 or .3 or .4
What would be a good way to get this outcome?
